When two people, whether mentally challenged, or intoxicated, or both, decide to get into a fight by trying to do the moves of various martial arts, only to awkwardly fall over themselves doing kicks and flips in the most uncoordinated and clumsy manner. Often involves the two participants ripping off their shirts and yelling like in a cheap Kung Fu movie.
"At the party, two dudes got wasted and started to argue - later they were fighting in the parking lot. Both were trying Dumb Fu, but got more hurt hitting the ground or pulling their muscles doing these crazy moves, than actually hitting each other! It was so funny to watch!"
